English is not my native language; I probably should have written "that the speed-up *from* a manual assembler implementation compared to a generated interpreter is about 30%"; the point is that the speedup is small but at least demonstrates that assembler programming apparently isn't worth it any longer.

Apparently I misinterpreted their paper concerning the JIT; as pointed out by others they indeed run separate measurements with baseline JIT on and off; so apparently it was off for the measurement I referred to. All in all it confirms that even for the JIT case assembler programming isn't worth it.
